As such, this Foreword may contain material that has not been subjected to public review or a consensus p

The Alliance for Telecommunication Industry Solutions (ATIS) serves the public through improved understanding between providers, customers, and manufacturers. The Sustainability in Telecom: Energy and Pr

5、otection (STEP) Committee formerly the Network Interface, Power, and Protection (NIPP) Committee engages industry expertise to develop standards and technical reports for telecommunications equipment and environments in the areas of energy efficiency, environmental impacts, power, and protection. Th

6、e work products of STEP enable vendors, operators, and their customers to deploy and operate reliable, environmentally sustainable, energy efficient communications technologies. STEP is committed to proactive engagement with national, regional, and international standards development organizations a

7、nd forums that share its scope of work. ANSI guidelines specify two categories of requirements: mandatory and recommendation. The mandatory requirements are designated by the word shall and recommendations by the word should. Where both a mandatory requirement and a recommendation are specified for

8、the same criterion, the recommendation represents a goal currently identifiable as having distinct compatibility or performance advantages. Suggestions for improvement of this document are welcome. They should be sent to the Alliance for Telecommunications Industry Solutions, STEP, 1200 G Street NW,

Fuller, STEP Vice Chair (AT loose fasteners and components; deformed seals; failed, loose, or broken components;

10、mechanical misalignment; cracked or broken structures; fretting or corrosion in bearings; migration of particles or failed components; particles or failed components lodged in circuitry or mechanisms; etc. 3.1.7 Relative Humidity: The ratio, expressed in percent, of the amount of atmospheric moistur

13、ease hardware and changes occur prior to release, the changes must be analyzed to determine if they may reasonably impact the outcome of the tests. If a significant impact is indicated, the testing shall be repeated on released hardware. 4.1 Equipment Test Categories and Configurations Equipment bei

14、ng subjected to operational vibration testing shall be defined into one of the following categories. Only the test method and acceptance criteria for the selected category shall be applied throughout the testing. NOTE: These categories and configurations are taken from ATIS-0600329 and can be perfor

15、med in conjunction with earthquake resistance testing. 4.1.1 Indoor Equipment Category A Shelf level equipment 100. Bandwidth 5 Hz. Overall grms 1 dB. Sinusoidal Vibration The tolerance allowed for vibration is 1 dB. Frequency 1%. 5 Test Matrix Random vibration is usually considered to represent a m

16、ore realistic vibration characteristic compared with sinusoidal. Random vibration shall be used as the environmental parameter unless significant sinusoidal vibration is known to be present in a particular application/installation. In this case, it may be desirable to test the equipment using these

17、sinusoidal waveforms, especially if it cannot be determined if the resonant frequencies of the equipment are outside of the known vibration frequencies. In all cases, pole mounted equipment shall be tested to the sinusoidal vibration requirement. Table 5.1: Test Matrix Test Levels Indoor Location In

Vibration Control System The vibration control system shall be capable of producing a random vibration signal with Gaussian distribution over the range of 4 to 200 Hz with a tolerance of 3 dB. The resolution of the random analysis shall be no greater than 5 Hz. If using a digita

The vibration control system should be capable of accepting a correction factor to accept variances in accelerometer outputs. 6.1.2 Support Equipment Support equipment should be appropriate for co
